STEAM-TRAP.

SPECIFICATION forming' part of Letters Patent No. 406,875, dated July 16, 1889.

Application filed March ll, 1889. Serial No. 302,869. (No model.)

To all whom t may concern.-

Be it known that I, CHARLES A. CARLETON, of \Vestb1'ook, in the county of Cumberland, State of Maine, have invented a certain new and useful Improvement in Steam-'Flaps of which the following is a description sufiiciently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying' drawings, forming part of this specification, in which- Figure 1 is a vertical transverse section of my improved trap; Fig. 2, a plan view of the bottom of the trap removed Fig'. 3, a top plan view of the dome detached; Fig. i, an elevation of the valve removed Fig'. 5, a section taken on line o: in Fig'. 1; and Fig. 6 a sectional View illustrating means for guiding the float.

Like letters and figures of reference indicate corresponding parts in the different iigures of the drawings.

My invention relates to that class of traps which are automatic in their action; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being' to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the body of the trap, and B the valve. The body of the trap consists of a cylindrical box having an inwardly-projecting annular fiange d at each end. A cap-plate f is secured by bolts g to the flange d at the top of the trap, said plate having` a central screw-threaded opening 71, for receiving a steam-pipe.

On the inner face of the plate f are three downwardly-projecting lugs fz', to the lower ends of which a circular dome O is secured, said dome being' disposed directly under the inlet 71. A threaded opening 26 is formed in the body A, to which an air-valve may be attached.

A plate k is secured by bolts g to the opposite ange d, and is extended downward eentrally at mf, said extension being provided with a threaded outlet-opening l. rlhe body 13, top plate f, and bottom plate 7.3 constitute the steam-trap chamber.

A circular valveopenin g p, Fig. 2, is formed in the plate 7c and opens into a semicircular valve-chamber r, formed in the extension m and connecting the valve-opening with the outlet I. A semicircular valve-ehamber t is formed in the extension m, its upper end opening through the plate 7c into the body of the trap around the valve-opening p. The chalnber t is extended horizontally in its lower portion between the upper and lower portions of the chamber fr, being separated therefrom bya partition i. -A valve-opening w (see Fig. 5) is formed in the partition o, in alignment with the opening p in the plate 7c, and connects the chamber t with the chamber r. An ordinary drip-cock 25 is disposed in the extension m and leads into the chamber t.

The valve B consists of a circular body porltion 15, provided on its upper end and near its lower end with annular flanges 16 and 17, said iianges being respectively fitted to work tightly in the valve-openings p w. The lower surfaces 1S of the flanges 16 and 17 are construeted slanting or diagonal, as best seen in Fig. i, so that said surfaces will be on planes inclined tothe planes of the plate 7s and partition z', whereby said valves will open and close gradually and with greater ease.

From the edge 1S of the Iiange 16 parallel guides or flanges 19 project at intervals, said guides being arranged longitudinally on the body 15. Similar guides QO-project from the corresponding edge of the flange 17 and form legs which rest upon the horizontal portion o2 of the partition `o and support the valve when seated, as shown in Fig. 1. A vertical valve-stem 2l is secured to the upper end of the valve B and projects into the body of the trap. A ball or float D is secured to the top of the stem 2l and is disposed direct-ly under the dome O. l

In the use of my improvement the trap is connected with the steam-pipes by the inlet 7L in the usual manner. The Water from the IOO condensed steam in the pipes entering the body of the trap through the inlet 7L strikes the top of the dome C and is deflected thereby from the iloat D. When sufficient Water has collected in the trap, it causes the Iioat to rise, carrying with it the Valve B, and permitting the Water to flow through the valve-openings p w and chambers r t into the outlet Z. Sufficient Water having thus been drawn off so that the ball D Will not iioat, the valve Will reseat itself and close the valve-openings. The dome C acts as a stop to prevent the ball from rising too high and thus Withdraw the valve too far from the openings p w.

In Fig. 6 the float D is represented as provided at its top with a pin 27, Which Works vertically in a socket 28, formed centrally in the dome C, the purpose of said pin being to guide the float and prevent the stem 2l from breaking or bending during transportation. y

Having thus explained my invention, what I claim is- In a steam trap, .the combination of a stearn-trap chamber provided with an inlet in its top, a dome secured Within Said steamtrap chamber opposite said inlet, two semiannular valve-chambers in the bottom of said body connected by a circular valve-opening, one of said valve-chambers opening directly into the trap-chamber and the other being CHARLES A. CARLETON.
